You'll need to experiment with line spacing value. Go to Format > Paragraph.
Set the line spacing to 'Exactly' then set the At value to the distance
between the horizontal lines on your paper (72pt = 1 inch), to the nearest
half point.
It's *very* hard to get this right (or rather, *very* time-consuming). You
might be better off printing the lines yourself as part of the document, and
print onto plain yellow paper.
